TIMECONTBOLLED SWITCH.

To all whom it may comm 1 Be itknown that I. Gannon R.

As is usual, a thumb switch 15 is provided'whereby the lights may be controlled manually. When thelights are to remain illuminated until a certain-time, the switch is turned off as shown'in Fig. 2 and the member 5 is set manually (b means to he described) in the position disc osed in said figure, the alarm of the clock-having been set at the proper time.

15 Thus, when this time is reached and the shaftxgates in the'direction of the arrows in ;-the spring -10 will be placed under tension and'the moment the tappet 11 forces downwardly on the left hand sleeve 7, the frictional engagement between the contacts 8 and 9 will be overcome and the spring will shift the member 5 to the position shown in Fig. 3, wherein one 'of its contacts 8 is frietionally 'e'n with the dummy contact 9. The notation iof the shaft 2 is now checked by contact ofigs winding key 16 with a stop pin 17 cari' iefd'by th'e bell 3, said key having moved froirr'iithe full line position' shown in 1 Fig.1 to the dotted line osition while the operation-above desci'i has .taken place. en novfithe member is to be again set as shown in Fig; 2-,.the'key 16 will-be'tur'ned in a clockwise direction, thus rewinding the alarm .sp'ring, the ljnovement of the key in If the 'ii i vention; is'Ttb be used for closing the circuit of-tlieglights at a. predetermined time, the 5' is set as shown in Fig. 3, but the'ke'y f16'j'is moved counter-clockwise -mg said key toithe shaft as shown. bus,

when said' 81iaft -2 rotates the necessa amount, thei nember 5 will be suddenly shifted from-fitsf'engagement. with the dummy contact 9 into contact with the two devices 9, whereupon. the circuit of the lights 14 will be completed. The movement of the shaft 2 during this operation, will be'limited by a third stop pin 19 as shown by the dot and dash lines in F ig; 1.

As clearlyshown in the several figures of the drawings, the key' 16 extends in opposite directions from the shaft 2 for engagement with the numerous stops 17, 18 and 19 as occasion may demand, the pivotal connection between the key and the shaft being such' as to allow said key to be tilted to an extent great enough toclear the intermediate stop 17, but the stops 18 and 19 are of such a leng th' as toprevent movement .o 'f the aforesaid key past the same.

- From the foregoing description, taken in connetion with 'the accompanying drawdirectipn being limited by a stop pin 18.'

manually set in ber with the dummy contact, andf'stop-iinehi ings, the construction, manner of operation and numerous advantages of the improved switch mechanism will be readily understood without requiring a more extended explanation. In conclusion, however, I wish to state that although the invention is shown applied in the circuit of a number of electric lights, its'application need not be limited to this use. Furthermore, I have shown numerous structural details for illustrative purposes, and above have described such de tails. It is manifest, however. that numerous changes may be made within the scope of the appended claims.
